Features 
• High Kv valves

mean lower water resistance in the same designed flow rate to save energy

• Compact internal movement structure to reduce space requirement for intallation

• Numeric handwheel

provider easy operation of the setting and the preset value during thr  balancing commissioning process

• Self-sealing test ports

for differential pressure meansurement

• Zero leaking anf compelete close off design

peovide compelete close off of pipework during the commissioning process or system maintenance
